[0021] Beneficial Effects

[0022] The present invention provides a multi-directional display system for digital exhibition models, which has the following beneficial effects compared with the prior art:

[0023] 1. The placement plate performs linear motion under the push of the model's own gravity. The placement plate pushes the turntable through the support mechanism to drive the partition to squeeze the elastic member A and slide along the device body. The turntable drives the spindle to perform linear motion in the vertical direction. The spindle pushes the gear on the gear set to mesh with the gear A according to the weight of the model. At this time, the driving member drives the spindle to rotate through the gear A and the gear set to cause the placement plate to automatically adjust the speed in the vertical direction according to its own weight. At the same time, the spindle drives the placement plate to rotate through the turntable. The spindle pushes the push rod through the pushing assembly to perform linear motion in the vertical direction. The push rod drives the placement plate to tilt in the horizontal direction to cause the model on the placement plate to tilt, thereby realizing a multi-directional display of the model.

[0024] 2. When the model is an irregular object, the center of gravity of the model shifts under the push of the pushing component. When the center of gravity is located outside the circumference of the placement plate, the spindle performs linear motion with thread changes in the device body. The spindle pushes the gears in the gear set to alternately mesh with gear A and the pushing component to perform synchronous motion, causing the center of gravity of the model to change continuously and causing it to rotate irregularly in space, thereby achieving the technical effect of fully displaying the heterogeneous model.
